Kristen Stewart spends Valentine's Day alone

Kristen Stewart did not visit her longtime boyfriend/Twilight Saga co-star, Robert Pattinson, on his movie set in Australia in order for them to spend Valentine's Day together.

As harsh as it sounds, this is not because the couple's relationship is rocky, E! News confirms.

A source linked to the pair confirms that Stewart will not travel to Australia for Valentine's Day, purely because of the remaining time Pattinson has left filming, and "she is smart enough to know that if she goes to visit it will bring too much unwanted attention to the film."

Pattinson has been stationed in Adelaide, Australia, while he shoots his newest movie, The Rover, and has less than two weeks left on the set. The actor will be back to L.A. once the shooting is wrapped.

Despite all of this, Pattinson reportedly took the job in Australia to give a trial separation from Stewart. He wanted to reevaluate their relationship and is concentrating on work at the same time, Hollywood Life reported.

After Stewart's affair with Snow White and the Huntsman director Rupert Sanders, it seems like Pattinson has been ready to pull the plug on their relationship.
